Determining the Liku Kalibrabassi Debit (Rating Curve) in the Dry Season in the Deli Watershed (DAS)

Introduction

The Deli Watershed (DAS) is a vital region for water resource management, and understanding the relationship between water level and discharge is crucial for efficient planning and management of river flow. The Liku Kalibrabassi Debit, or rating curve, is a curve that shows the relationship between water level and river discharge, which is essential for predicting the amount of discharge in the river. This study aims to determine the discharge calibration equation in the Deli Watershed (DAS) during the dry season.

Background

The Deli Watershed (DAS) is a significant region for water resource management, and the river discharge in this area shows a significant variation of values. The river water discharge at the spas doulu location ranges between 0.62 to 1.54 m³/sec, with an average of 28.28 m³/sec. These variations show significant changes in river flow that can be influenced by various factors, including rainfall and the influence of human activity around the watershed.

Methodology

The methods used in this study include measurement of river water discharge and water level data collection using a water level logger, with a frequency of observations at least twice a week. Regression analysis is carried out to test the relationship between discharge and water level value using various models, namely linear models, polynomials, rank, logarithmic, and exponential.

Results

The results show that the polynomial model has the best compatibility with discharge data, with a very strong correlation rate, shown by the highest correlation coefficient of 0.936 and the root mean square error (RMSE) of 0.01. This indicates that this model can accurately predict river discharge based on water level.

Rating Curve Equation

The rating curve equation resulting from this study is:

Q=37.58(H)2−8,019(H)+0.869{ Q = 37.58 (H)^2 - 8,019 (H) + 0.869 }

With this equation, we can calculate river discharge under certain conditions just by measuring water level. This is very useful for water resource managers in the planning and management of river flow, especially in the dry season when water discharge tends to be reduced.

Conclusion

Through this research, it is expected to make a significant contribution to the understanding and management of the Deli watershed, as well as being a reference for similar studies in other regions. By understanding the relationship between water level and discharge, water resource management can be done more efficiently, so that it can maintain the sustainability of river ecosystems and support the needs of the community that depends on these water resources.

Implications

The findings of this study have significant implications for water resource management in the Deli Watershed (DAS). The rating curve equation can be used to predict river discharge based on water level, which can help water resource managers to plan and manage river flow more efficiently. This can lead to the maintenance of the sustainability of river ecosystems and support the needs of the community that depends on these water resources.

Future Research Directions

Future research directions include:

  • Validation of the rating curve equation: The rating curve equation should be validated using data from other locations in the Deli Watershed (DAS) to ensure its accuracy and applicability.
  • Incorporation of other factors: The rating curve equation should be modified to incorporate other factors that influence river discharge, such as rainfall and human activity.
  • Development of a more accurate model: A more accurate model should be developed to predict river discharge based on water level, which can be achieved by incorporating more data and using advanced statistical techniques.
